VOTING-MACHINE.

Specification of Letters Patent.

Patented June 17, 1919.

Application filed May 24, 1917. Serial N 0. 170,722.

To all whom it may concern I Be it known that I, SYVER Lon, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Voting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to multiplex voting machines of the general character disclosed and broadly claimed in my prior Patent 1,039,419, of date, September 24, 1912.

The present invention is directed chiefly to improvements in the machine setting and locking mechanism, to-wit, in the lever and lock mechanism controlled by a voter and by the election judge or attendant; and in this respect, it is, particularly, an improvement on the mechanism disclosed and claimed in my prior Patent 1,158,518, of date, November 2nd, 1915, entitled Multiplex voting machine.

Machine frame and support therefor. The relatively fixed main framework of the machine' is in the nature of a skeleton 2 and four tubular columns 3 3",, 3, and 3 that rigidly connect the said frames. These upper and lower head frames have inwardly converging spokes 3 that connect to hubs in herewith and entitled Truck, etc.- Also,

the said main frame is preferably formed with hinged segmental doors or folding leaves 6 adapted, when the machine is out of use, to close up the machine to protect the register actuators or case and adapted, when the machine is in use, to be pulled out and used as part of the voting booths, all as more fully disclosed in my companion application filed of even date herewith, and entitled Folding booth and frame for voting machines.

Registers 0r ta lhies and support therefor.

The axial shaft 4: (see particularly Figs. 2 and a inclusive) carries the so-called'tally support. This register support comprises upper main and supplemental register sup porting frames. The said main 7 register supporting frame is made up of upper and lower wheel-like heads 5 rigidly secured to the axle shaft 4 and connected at. their outer portions, as shown, by three upright tie-rods 6. This frame 5-6, as is evident, must 7 therefore partake of the rotary movements of the axial shaft 4:, but has no vertical movement in respect thereto. The supplemental register supportingframe is made up of upper and lower segmental skeleton heads 7 and '7 respectively, thatare tied together loya multiplicity of vertical channel bars 8 and tie rods 8 (see particularly Figs. 2, 21 and 26) which, together with said heads, are mounted for limited vertical movements on two of the tie-rods 6 of said main register supporting frame. The said supple mental register supporting frame is, at least in part, supported by spring connections 9 (see Fig. 21) attached to the lower head 7 and to the upper head 5. The'said horizontal frame, of course, partakes of the horizontal rotary or oscillatory movements of the said main register supporting frame.

Vertical reciprocating movements of the said supplemental register supporting frame, in respect to the said main register supporting frame, is produced through means which will now be described inpart, attention being directed particularly to Figs. 21 and 26.. V

The numeral 10 indicates a crank rod preferably made longitudinally adjustable, the

lower end of which is pivotally connected 7 to the lower head frame 7 of the supple mental register supporting frame by a pin 10' and the upper end of which is journaled on a wrist pin 11 of a short horizontal crank shaft 11 that is journaled in a bearing 12 rigidly secured to the upper head 5 of the main register supporting frame. This crank shaft 11, at its outer end, is provided with a spur gear 13 that is operated upon by means hereinafter described. The crank shaft 11 has a disk-like flange 11 formed at one point only with a notch 11 that is normally engaged by a spring-pressed latch 14 intermediately pivoted to the upper head 5 and normally holding the wrist pm 11 in a raised position, so that the said supplemental register supporting frame will be normally held in raised position in respect to the main register supporting frame. The outer free end of the latch 14 has a notch 14L for an important purpose which will hereinafter appear (see Fig. 26). Here it may be further noted that the notched free end of the latch 14 is adapted to be depressed into a large clearance notch 5* (see Figs. 21 and 26) formed in the upper edge of the annular outer rim of the upper head 5.

The registers or tallies are indicated, as entireties, by the nimieral 15 (see particularly Figs. 24, 25 and 26) and their cases are rigidly secured to the channel bars 8 in vertical columns and preferably in an arrangement more fully disclosed in my two prior patents above identified. member of each register is connected to move with a so-called escapement wheel 16 that is provided with ten laterally projecting triangular cam-acting escapement lugs 16. The hubs 16 that connect these escapement wheels 16 to the respective unit members of the registers is, in Figs. 24 and 25, shown as serrated or toothed for a purpose which need not, however, be here considered, other than to state in a general way that it enables the register to be quickly reset.

For cooperation with each escapement wheel 16, there is provided an escapement lever 17 that is pivoted at one end to a proj ection of the cooperating register case, and at its intermediate portion, is provided with laterally offset double-ended escapement lugs 17, the ends of which are reversely beveled so that the escapement wheel will be given a half step, or one-half unit of rotation under downward movement of said lever and the second half step unit rotates under upward movement of said lever. The number of register supporting bars 8, as well as the number of registers on each bar may, of course, be varied, but the total number of registers should, however, correspond to the number of register actuators or keys in any one of the several sets to be hereinafter described.

The free ends of the escapement levers 17 project beyond upright bars 18 shown as of channel form, rigidly secured to the upper and lower heads 5 of the main register sup- The unit porting frame; and these bars 18 are provided with'lugs or lateral projections 18 (see particularly Figs. 21, 25 and 26) with which the said levers are adapted to be engaged and by which said levers will be forced downward when the supplemental register supporting frame is moved from its lower back to its normal or raised position. The registers above noted are, of course, for registering the individual votes cast by the use of the machine.

Keyboard and register actuators or keys.

The register actuators or keys, which, as before stated, are arranged in vertical columns and in horizontal rows, are of the general arrangement and character disclosed and broadly claimed in my prior patents above identified and preferably are of the improved construction disclosed and claimed in my companion application filed of even date herewith and entitled Keyboard mechanism for voting machines.

In this preferred arrangement of the multipleX voting machine, the said register actuators or keys are arranged in three independent groups, so that three voters may in dependently set the register actuators in the respective groups in a manner which will represent the total vote they desire to cast.

For the purposes of this case it is not necessary to describe in detail, all of the features of the said keyboard mechanism. In Fig. 27, a portion of one of the groups of register actuators is shown in elevation and in Fig. 25 several'of the register actuators and coiiperating framework, are partly in elevation and partly in horizontal section. It may, however, be here further stated that the register actuators of the several groups are in supplemental arrangement; that the supporting blocks or frame element therefor are contained in the vertical space between the lower head 1 and upper head 2 of the main frame, and within the annular space between the inner and outer annular margins of said frames; and that what may be treated as the first group, in a circumferential direction, is between the columns 3" and 3, that the second group, likewise, is be tween the columns 3 and 3, and that the third group is between the columns 3 and 3, attention being directed to Fig. 1, in which, for the sake of clearness, no attempt has been made to show the said register actuators and escapement lever 17, as indicated in Figs. 25 and 26.

WVith the above comments, the said register actuators and immediately associated parts may be briefly described as follows; attention being directed particularly to Figs. 1", 25, 25, 26 and 27.

Each complete register actuator comprises a register operating lever 19, and a finger actuated lever or key 20. The register actuators are arranged in vertical columns and of date, October 28, 1902.

These vertical eXpansible vote limiting elements and 21 are rotatably mounted on the framework of the machine. Preferably, they are thus rotatably mounted in cylindrical seats formed in interlocking skeleton'frame-formmg blocks 22 best shown 111 Fig. and disclosed and claimed in my companion application filed of even date herewith and entitled Keyboard mechanism for voting machines. The levers 20 are rotatably mounted on hubs 23 (see Fig. 25?) which, in turn, are arranged in vertical coluinns upon so-called re-setting shafts 24.

These re-setting shafts 24, as shown, are tubular and hexagonal and they are set upright and rotatably mounted in the base and head structures of segmental frames 25 (see particularly Fig. 10). In the three-party voting machine, there are three of these segmental sections 25, which, when the machine is operative, are alined in cylindrical arrangement. In practice, these segmental frame sections 25 will be arranged to swing into open positions, as disclosed in my prior Patent 1,039,419, of date, September 2%, 1912. This swinging feature, however, constitutes no part of the present invention and need not be further considered. The interlocking frame blocks 22, it should be understood, however, are secured to their respective segmental frames 25. As shown, the said blocks 22 are telescoped onto upright tubes 26, the upper and lower ends of which are anchored to the said segmental frames.

The hubs 23' are adapted to be given com-.

mon rotary movements with the respective shafts 2 1, through gears 27 (see Fig. 10) secured on'the upper ends of the re-setting shafts 241. The pinions 27 of the re-setting shafts for each particular booth, or in other words, for each particular frame 25, mesh with teeth on segmental racks 28 that are mounted for sliding movements on the arc of curves through keepers 29 secured on the lower plates of the upper portions of the said frames 25. The means for imparting sliding movements to the respective racks 28 will be hereafter described.

The lever 20 of each register actuator has a projecting arm with a pin 30 that works 7 in* the slotted arm of the lever 19 of the same actuator (see Fig. 25*). In Fig. 25*, the reg in the booths.

ister actuator at the right is in its set or 01)- erative position. In this set or operative position shown-at the right, the projecting end of the lever 19 will be thrown directly under.

' the escapement lever 17 of the corresponding register or tally, providing the register support has been properly positionedfor registration of votes. This action will be more fully brought out in the description of the operation. It will, of course, be understood that the'finger-actuated lever or key 20 will be moved from its normal position at the left into its set position at the right, by the finger of the voter.

JLtdfl actuated device's, voters registering crank and cooperatmg mcchamsm.

For oscillating the rotary register sup-poi" so as to carry the registers into alinement with any one of the three groups of register actuators, there is provided a so-oalled positioning crank (see particularly Figs. 2, 3, 4t and 5) which is located between two of the booths and in position to be easily reached by the election judge or attendant, but by no one of the three voters from with- This crank 33 is secured to the outer end of a radial shaft 34: journaled in suitable hearings on the upper head 2 of the machine frame and providedat its inner end with a beveled pinion 35 that meshes with a beveled gear 36 secured to the shaft 4 of the said rotary register sup-port. This crank 33 (see Fig. 3) has a spring-pressed lock pin 37 that is adapted to engage a lock notch 38 in a lock disk 38 that is rigidly secured to the said upper head 2. Whenever the lock pin 37 is engaged with the lock seat 38", the registers will be secured in proper position for cooperation withone or the other of the three independent sets of register actuators. Otherwise stated, one rotation of the crank 33 will move the registers from alinement with one set of register actuators. 1 i

On the upper or head portion of each of the three segmental frames'25 is a short radial shaft 39 (see particularly Figs. 10, 11, 12, 17, 18, 19 and 26) which, at its outer end, is provided with a so-called voters registering crank 40. This crank 410, when themachine is free for the registration of votes by the voter, stands in the position indicated by full linesin Figs. 11 and 27, and is then held against the upper edge of a stop 11 on the upper head of the corresponding segmental a
